2 Claims. (CI. 81-39) vis t consists inthe arrangement, combination and details of construction disclosed in the drawings and specification, and then more particularly pointed out in the appended claims. 1

In the drawings:

Figure 1 is a plan view, partly broken away and in section, of a vise constructed according to an embodiment of this invention.

Figure 2 is a detailed side elevation of the vise.

Figure 3 is a sectional view taken on the line 3-3 of Figure 1.

Figure 4 is a sectional view taken on the line 4-4 of Figure3, but omits the workpiece.

Figure 5 is a fragmentary plan view of the vise showing the same in clamping position with respect to a small diameter work piece.

Referring to the drawings, the numeral designates generally a flat base which is provided along the opposite longitudinal edges thereof with pairs of slots 13 whereby the base 10 may be clamped to a table or flat surface. The base 10 has fixedly secured thereto, adjacent one end thereof, a stationary jaw structure generally indicated at 11. The jaw structure 11 is formed of a body or block 12 which is fixed by fastening means 14 to the upper side of the base 10. The body or block 12 is provided with a slot 15 extending lengthwise of the \block 12 and transversely of the base 10. The body or :block 12 is also formed with a pair of end slots 16. The :body or block 12 forms per se a fixed jaw member and the jaw member 12 has pivotally secured thereto, pivoted jaw members 17 and 18. The jaw members 17 and 18 are substantially triangular in plan, and jaw member 17 has fixed thereto a vertically disposed bushing 19 through which a pivot pin 20 extends. The jaw member 18 is a double jaw member embodying upper and lower jaws 18 and 18* which are spaced apart a distance sufiicient such that when the jaws 17 and 18 are swung towards each other they may be disposed in overlapping relation with jaw member 17 loosely engaging between the jaws 18 and 18 A movable or adjustable jaw member generally indicated at 20 is mounted on the upper side of the base 10 and is slidably secured to the base, 10 by means of a headed bolt 21 which slidably engages in a T-shaped slot 22 which is formed lengthwise of the base 10. The jaw member 20 is formed of a body 23 having a slot 24 extending lengthwise of the body 23 and transversely of 2,724,293 P atented Nov. 22, 1955 the base' 10*. The body"23 is also formed w th end slots 25. A pair of pivotedjaw'members.26 and27 are pivotally. secured to the body 23 in the end' slots 25 thereof and jaw member 26 isa; single jaw member which is adapted upon inward swinging of the two jaw members 26 and 27 to engage between the upper and lower jaw members 27 and 27', which form as a unit the jaw member 27. The jaws 27 and 27 are diagonally disposed with respect to the pair of jaws 18 and 18 so that when the movable jaw member 20 is moved close to the stationary jaw member 10, the pivoted jaw members carried thereby will overlap each other.

In other words, the single jaw member 17 will engage between the jaw members 27 and 27 and also between the two jaw members 18 and 18*. In like manner, the single jaw member 26 will not only engage between the two jaw members 27 and 27*, but will also engage between the two jaw members 18 and 18', as shown in Figure 5. The movable jaw member 20 is provided with upper and lower outwardly projecting lugs 28 and 29 respectively, between which a block 30 is secured.

The block 30 is secured by a pair of pins 31 and 32 which extend through the lugs 28 and 29' respectively. A screw shaft 33 is threaded through a fixed and upstanding nut 34 carried by one end of the base 10 and the screw shaft 33 is swiveled or rotatably mounted in the block 30 by forming a reduced diameter stud 35 on the shaft 30 and securing a washer 36 to the inner end of stud 35 by means of a fastening member 37. A thrust washer 38 is carried by the outer end of the stud 35 and bears against the outer side of the block 30.

The outer end of screw shaft 33 is formed with a polygonal stud 39 for receiving a crank or the like so that shaft 33 may be rotated to move jaw member 20 toward or from jaw member 11.

In the use and operation of this vise where a relatively large work piece, such as work piece 40 is to be clamped between the jaw members 11 and 20 and this work piece is either circular in cross-section or is formed with arcuate outer surfaces, the pivoted jaw members 17, 18, 26 and 27 are swung inwardly in inward convergent relation as shown in Figure 1. Shaft 33 is then turned to move jaw member 20 inwardly and thereby clamp the work piece 40 between the extended pivoted jaw members 17, 18, 26 and 27.

In the event the work piece is formed with fiat surfaces, the jaw members 17, 18, 26 and 27 may be swung outwardly to an inoperative position so that the confronting fiat faces 41 and 42 of the jaw members 11 and 20 will be in confronting position.

Where the article or work piece is relatively small in diameter such as shown at 40' in Figure 5, the jaw members 17, 18, 26 and 27 will swing inward in overlapping position relative to each other and with the single jaw members 17 and 26 engaging between the double jaw members 18 and 27.

With a vise structure as hereinbefore described, articles of various configurations may be tightly clamped to the base without the use of a jig or other specially formed clamping structure.

What is claimed is:

l. A vise comprising a base, a fixed jaw carried by said base, a movable jaw carried by said base, means adjusting said movable jaw, each jaw being formed of a body, a pivoted jaw member carried by said body adjacent one end thereof, and a pair of spaced parallel jaw members carried by said body adjacent the opposite end thereof, said first named jaw member being swingable between said pair of jaw members.

2. A vise comprising an elongated substantially rectangular base having a jaw fixedly mounted thereon adjacent one of its ends, a second jaw slidably mounted on said base for reciprocation towards and away from said first jaw, means on said base for efiecting said reciprocation of said second jaw, a-pivoted jaw member carried by said first jaw adjacent one end thereof and a pair of spaced parallel "pivoted jaw members mounted adjacent the other end of said first jaw, a pivoted jaw carried by said second jaw adjacent one end thereof, and a pair of spaced parallel jaw members pivotally mounted adjacent the other end of said second jaw, said first members being swingable between said pairs of jaw members.
